Diabetes mellitus has become the leading cause of ESRF in the United States. Patients with
diabetic nephropathy
suffer high cardiovascular morbidity and mortality. Because only 40% of diabetic patients eventually develop diabetic kidney disease, it may be possible to devise primary prevention measures targeted at the subset of patients at risk. Recently, a predisposition to hypertension, a family history of
diabetic nephropathy
, and a family history of CVD disease each have been associated independently with the development of diabetic renal complication in IDDM. Risk factors for macrovascular damage, including raised arterial BP,
dyslipidemia
, and insulin resistance, can be detected early in the course of progression to
diabetic nephropathy
. These risk indicators recently have been shown to be already present at the stage of normoalbuminuria in those patients who eventually will progress to microalbuminuria. Treatment of established renal disease can only delay the onset of ESRF, and lowering of microalbuminuria has been shown to retard the onset of persistent proteinuria. However, no study to date has demonstrated prevention of renal disease in these patients. The ultimate aim should, therefore, be the prevention of the transition from normoalbuminuria to microalbuminuria in individuals who are at higher risk of diabetic renal disease and CVD.

The primary aim of the management of hypertension should be to prevent coronary heart disease. Antihypertensive treatment should have a beneficial effect on the risk factors associated with coronary heart disease, particularly hypertension,
dyslipidemia
, hyperinsulinemia, and/or glucose intolerance. Other important risk factors include central obesity, left ventricular hypertrophy, hypokalemia, and smoking. In patients genetically predisposed to essential hypertension, metabolic alterations characterized by insulin resistance, hyperinsulinemia, and
dyslipidemia
tend to occur already before the development of hypertension, obesity, or redistribution of body fat. In the treatment of normotensive or borderline hypertensive diabetic patients, angiotensin-converting enzyme (ACE) inhibitors have shown superiority to other agents due to their antiproteinuric effect and their beneficial influence on the glomerular filtration rate. ACE inhibitor treatment of patients with overt
diabetic nephropathy
has been reported to reduce the risk of mortality and the need for dialysis or transplantation. Beta blockers and thiazide diuretics are still the 'gold standard' of antihypertensive therapy in non-diabetic patients, as they offer at least some prognostic benefit, while the influence of the newer antihypertensive drugs on morbidity and mortality in these patients is not yet known. Nevertheless, since practicing physicians have to treat patients rather than statistical numbers, the current trend towards a more individualized selection, including the newer antihypertensive drugs with consideration of their metabolic, cardiac, and renal action profile, is also difficult to rebut. ACE inhibitors and most calcium antagonists have already evolved as the preferred drugs for the treatment of hypertension in diabetics due to their favorable effects on some of the cardiovascular and renal risk factors.

Twenty-nine patients with insulin-dependent diabetes mellitus with similarly manifest renal involvement were examined to elucidate the role of
dyslipidemia
in
diabetic nephropathy
progress. Clinico-laboratory parameters (urinary albumin excretion, blood serum levels of total cholesterol, triglycerides, low, very low, and high density lipoprotein cholesterol) and morphologic changes in renal tissue biopsy specimens were analyzed. An increment of the number of large lipid incorporations was observed in various cells of renal glomeruli and interstitium, as well as a high prevalence of low density lipoprotein deposition in glomerular basal membranes and canaliculi as the renal process augmented in severity. Since lipids accumulating in glomerular structures may stimulate mesangial cell proliferation and mesangial matrix hyperproduction, the authors believe that
dyslipidemia
in diabetes mellitus may be conducive to a more rapid progress of renal disease.

To determine the mechanisms underlying
diabetic nephropathy
(DN) onset, a clinical and morphological study was initiated of 14 diabetics with insulin-dependent disease free of clinical renal manifestations. The patients were examined for intraglomerular hypertension, blood lipid spectrum and renal tissue morphology. In high intraglomerular hypertension, i. e. in renal functional reserve depletion, there is
dyslipidemia
with a characteristic significant rise in the levels of very low density lipoprotein cholesterol and low density lipoprotein cholesterol, in the value of atherogenic index. Morphologically, renal tissue of the hypertensive and dyslipidemic patients experienced hyperperfusion and massive lipid infiltration in glomerular cells. In contrast, renal tissue underwent only minimal nonspecific changes when intraglomerular hemodynamics and lipidemia were normal. The findings suggest that associated effects of intraglomerular hypertension and
dyslipidemia
may promote DN onset.

We retrospectively analyzed the courses of 37 non-insulin dependent diabetics (hemodialyzed:HD group) with end-stage renal disease (ESRD), to identify factors predisposing to renal failure. The factors analyzed were: diabetic (non-proliferative and proliferative) retinopathy, family histories of diabetes and hypertension, smoking,
dyslipidemia
, first examination proteinuria and non-compliance. These factors were statistically compared in 37 NIDDM without renal failure (non-HD group). There were no significant differences in age or duration of diabetes between the two groups. Significant differences (P < 0.001) were, however, recognized in diabetic proliferative retinopathy and hypertension between the two groups. Hypertension was present in 35/36 (97.2%) HD patients and in 21/36 (58.3%) non-HD patients. A family history of hypertension was recognized in 16/37 HD (43.2%) and in 7/33 (21.2%) non-HD (P < 0.05). Differences were recognized in HDL-cholesterol, LDL-cholesterol and TG levels (38.2 +/- 12.5 mg/dl and 56.7 +/- 18.5 mg/dl, 140.4 +/- 57.1 mg/dl and 115.6 +/- 33.6 mg/dl, 169.9 +/- 89.4 mg/dl and 115.7 +/- 75.1 mg/dl, in HD and non-HD, respectively, P < 0.05). First visit proteinuria was found in all HD patients, and in 6/34 (17.6%) non-HD. The difference in previous treatment refusal, for 7 or more years, was significant with 23/36 (58.9%) HD patients and only 1/25 (4.0%) non-HD patients (P < 0.001) having a history of prolonged non-compliance with diabetic treatment. Diabetic retinopathy, non-proliferative and proliferative, hypertension and a family history of hypertension, elevated triglyceride and LDL-cholesterol, low HDL-cholesterol, first visit proteinuria, and prolonged non-compliance correlated with progression to ESRD. We advocate expanding diabetic education to include prevention of complications such as
diabetic nephropathy

Diabetic nephropathy
is the single most common cause of end-stage renal disease in the United States. Recently, several major therapeutic interventions have been developed and shown to slow or halt the progression of renal failure in patients with diabetes and diabetic kidney disease. Studies have shown that in patients with insulin-dependent diabetes and proteinuria, lowering systemic blood pressure slows the rate of decline in renal function and improves patients' survival. In the recently completed trial of angiotensin converting enzyme (ACE) inhibition in
diabetic nephropathy
, ACE inhibitors were specifically shown to decrease dramatically the risk of doubling of serum creatinine or reaching a combined outcome of end-stage renal disease or death independent of their effect on systemic blood pressure. In studies with small numbers of patients, dietary protein restriction has also been shown to slow the rate of decline of renal function. New potential interventions currently undergoing study include treatment with aldose reductase inhibitors, treatment with inhibitors of the formation of advanced glycosylation end-products, treatment of
dyslipidemia
, and a variety of other less well-studied interventions.

Plasma lipoproteins (LP) may be identified on the basis of density properties or apolipoprotein (apo) composition. ApoB-containing LP occur in VLDL, IDL and LDL. There are several types of apoB-containing LP characterized by specific composition of minor apolipoproteins (apoC, apoE etc.) and lipid constituents (triglycerides and cholesterol), metabolic properties and relative atherogenicity. The alterations of lipoprotein metabolism in renal disease resulting in elevated levels of apoB-containing LP may be reflected in hyperlipidemia. Whereas nephrotic syndrome and heavy proteinuria are associated with increased formation of cholesterol-rich apoB-containing LP in LDL and VLDL, the characteristic feature in renal failure is the accumulation of intact or partially metabolised triglyceride-rich LP in IDL and VLDL. The potentially atherogenic apoB-containing LP have been linked to the pathogenic processes that result in progressive glomerular and interstitial lesions and ultimate loss of renal function. The mechanisms of injury are not fully understood. Receptor- and non-receptor mediated uptake of LP by mesangial cells may induce or accelerate proliferative and sclerotic processes in the glomerular mesangium that are analogous to atherosclerosis in the arterial wall. Changes in glomerular permeability can result in increased filtration of LP that may be internalized by tubular cells and elicit corresponding lesions in the interstitial tissues. The negative impact of proteinuria on the prognosis of renal disease could be mediated in part through an increased filtration of lipoproteins. Induction of hyperlipidemia accelerates glomerular and interstitial damage in experimental renal failure. This can be attenuated by treatment with hypolipemic agents. In patients, increased concentrations of apoB-containing LP are associated with more rapid progression of renal insufficiency in both primary renal disease and
diabetic nephropathy
. It is, however, presently not known to what extent treatment of the renal
dyslipidemia
can modify the progression of chronic renal failure. Experimental and clinical evidence suggest that apoB-containing LP may play a pathogenetic role in the progression of renal disease.

The treatment of the patient with diabetes, with or without hypertension, is complex and challenging. Hyperglycemic treatment should ideally not only control blood glucose, but also prevent the chronic complications and associated metabolic derangements that can lead to increased morbidity and mortality. Hypertensive treatment should not only decrease blood pressure, but also reduce the risk of macrovascular and microvascular disease. The use of antihypertensive agents that improve insulin resistance,
dyslipidemia
, glycemic control, and nephropathy is preferred whenever possible. The real key to success in the care of the hypertensive diabetic patient is adequate screening and appropriate, early treatment. Currently, there is ample evidence to support the use of intensive management with the goal of near-normalization of blood glucose levels in most patients with diabetes. Similarly, aggressive treatment of hypertension is the current standard. Accomplishing these goals helps to prevent the development of chronic diabetic complications, including nephropathy. ESRD need not be the inevitable outcome for individuals with early
diabetic nephropathy
. Interventions currently available that are targeted at the known modifiable risk factors underlying the development and progression of
diabetic nephropathy
offer the best hope for reducing the incidence and severity of this complication. Prevention of the complications of diabetes, including nephropathy, must be the goal for the future on behalf of all those who now have diabetes.

We studied 68 Japanese NIDDM patients (38 men and 30 women), aged 56.9+/-1.2 years (range 33-75 years), with a BMI of 23.1+/-0.5 kg/m2 without hypertension,
dyslipidemia
, and diabetic macroangiopathy for evaluating the relationship between serum soluble vascular cell adhesion molecule-1 (sVCAM-1) levels and the severity of diabetic retinopathy. Fundus examination was performed by an ophthalmologist using an ophthalmoscope, and the findings were graded as: (1) no signs of diabetic retinopathy (NDR), (2) background diabetic retinopathy (BDR), or (3) proliferative diabetic retinopathy (PDR). Serum sVCAM-1 levels were measured in duplicate by enzyme-linked immunosorbent assay using the soluble VCAM-1 KIT (R&D Systems Ltd., Ablingdon, Oxfordshire, UK). There was no difference in serum sVCAM-1 levels between patients with BDR (n = 17) and patients with NDR (n = 40) (1035.3+/-104.4 and 978.8+/-48.9 ng/ml, respectively, P = 0.8), but patients with PDR (n = 11) showed a significant increase of serum sVCAM-1 levels compared with patients with NDR (1281.8+/-166.3 and 978.8+/-48.9 ng/ml, respectively, P = 0.02). Although serum sVCAM-1 levels were correlated, not only with age but also with the known diabetic duration (r = 0.39, P = 0.001, and r = 0.40, P = 0.0007, respectively), age-adjusted sVCAM-1 levels were still significantly higher in the PDR group than in the NDR group. In contrast. serum sVCAM-1 levels were not related to the presence of
diabetic nephropathy
or HbA1c levels. Our results suggest that sVCAM-1 might be implicated in the development of the diabetic retinopathy, and measurement of serum sVCAM-1 levels in NIDDM patients maybe clinically useful for assessing the severity and possibly the activity of diabetic retinopathy.

Hyperglycemia may lead to atherosclerosis by different pathogenic mechanisms. Nonenzymatic glycation and oxidation of LDL may increase its atherogenicity. Glycation may modify some arterial wall structural proteins. Increased blood glucose leads to hypertriglyceridemia which results in decrease of HDL-cholesterol level and in increase of atherogenic dense LDL particles. Hyperglycemia also adversely affects processes of platelet aggregation, hemocoagulation and fibrinolysis. It accelerates the development of
diabetic nephropathy
--a condition with a high prevalence of macrovascular diseases. Prospective epidemiologic studies have shown that diabetic patients in worse metabolic control had an increased cardiovascular morbidity and mortality. Therapeutic randomized studies in type 1 (DCCT) and type 2 (UKPDS) diabetic patients have shown that better diabetes control had a preventive effect against development of microvascular complications. The incidence of macrovascular complications both in type 1 diabetic patients on intensive insulin or sulfonylurea treatment has been decreased on the level of borderline statistical significance. Metformin lead to a significant decrease in myocardial infarction incidence in the subgroup of obese type 2 diabetic patients. In conclusion, maximal possible metabolic control of diabetes prevents the development of microvascular complication, but more impressive decrease in macrovascular disease incidence probably requires to affect another important risk factors for atherosclerosis, such as
dyslipidemia
and hypertension.
